SD42525_Datasheet 32V/1A, HIGH-EFFICIENCY HYSTERESIS LED DRIVER WITH BUILT-IN MOSFET DESCRIPTION SD42525 is a step-down constant current converter with inductance current continuous-conduction mode, it is used for driving LED or LEDs in series. The output current is adjustable which is up to 1A in 6~32V input voltage range. LED whose power is tens of watts can be driven by SD42525 with different input voltages and peripheral elements. With built-in power switch, average current of LED can be set through external high-side current sensing. Analog dimming and wide range PWM dimming are available through pin DIM and soft-start time can be set by capacitor value which is connected between pin DIM and ground.
